As another data point I also have a VP6 (2x PIII 700)
Up until Tuesday only had a serial mouse, but now has a PS/2
Never any problems before (on most 2.4.x kernels) now running 2.4.17 + Int +
XFS and haven't seen any problems after a couple of heavy desktop session ~6
hours.
But I can keep an eye out, not at the machine right now but can forward on
some info tonight if required.
